Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to systems for delivering inhalable aerosols, as well as components of such systems. This system is particularly suitable as a smoking device for producing smoke aerosols for smokers.

[0002] When smoking conventional cigarettes, most tobaccos burn during periods of inactivity, not during smoking. This creates so-called Nebenstromuch, which often makes nonsmokers uncomfortable.

[0003] To overcome this problem, a number of new smoking articles have been proposed. The principle common to such developments is that what is used to emit the smoke aerosol is another source of energy, rather than the heat of combustion of tobacco. Thereby, sidestream smoke is largely avoided. In smoking devices proposed for aerosol formation, alternative materials are often used instead of tobacco, such as special leaf tobacco or carrier materials treated with aroma substances.

For example, cigarette-like smoking devices are disclosed in US Pat. Nos. 5,060,666 and 5,605,666.
No. 5,099,861 wherein the thermal energy of the red-burning carbon component is aerosol-forming material, which, in addition to tobacco or tobacco extract, has an aroma. And containing an aerosol-forming agent (eg, glycerin). The combustion gases of the heating element are inhaled with the smoke aerosol, which causes an increase in carbon monoxide absorption by the smoker. In addition, the entire smoking device must be discarded after smoking, resulting in increased residue generation of complex compositions and associated disposal problems.

[0005] Devices are also known in which a substrate portion is heated by electrical energy to emit a smoke aerosol. Such devices, due to their size and weight, must be held by hand and cannot be carried by mouth; however, US Pat.
1,369. Other cigarette-like smoking devices in which a special tobacco aroma is electrically heated by the battery current to produce an inhalable aerosol in the process are disclosed in U.S. Patent Nos. 5,095,921 and 5,595. 179,
No. 666 and 5,269,327. A cigarette for an electrically heated smoking system is shown in U.S. Patent No. 5,499,636. All of these devices, however, are relatively heavy and awkward.

[0006] A smoking device in which nicotine and a tobacco mimetic are heated and inhaled indirectly, for example via a combustible cellulose foam, is known from US Pat. No. 4,474,181.

[0007] WO 97/48294 shows yet another system for producing inhalable aerosols. A burner and a fuel reservoir, including heating means for powering the burner, are located in a housing for hand holding. The rising hot combustion gases flow through a heat exchanger in which ventilation channels are arranged.
These ventilation channels are connected at one end to the outside air and open at the other end to a pipe-like flow channel (which starts from the upper area of the housing) and at its free end a mouse Designed as a piece.
The middle part of the flow channel is occupied by a base part, which is indirectly heated by air sucked by the user and heated via the heat exchanger, releasing the aerosol. This system is also relatively heavy and awkward, and must be opened to insert a new substrate portion.

It is an object of the present invention to create a light, handleable system that can be carried in the mouth of a user, the system including a reusable inhaler and, in particular, a conventional cigarette. It can be provided as a smoking device that gives a taste similar to that of cigarettes, but does not generate sidestream smoke between smoking operations during use.

This object is achieved by a system having the features of claim 1, which system comprises an inhalation device having the features of claim 26 and a substrate having the features of claim 28. With parts. Advantageous forms of the invention emerge from the dependent claims.

The system according to the invention for delivering an inhalable aerosol has an inhalation device, which has a rod-like housing with a rear mouth area and a front area. At the front of the housing is arranged a substrate holder, which is
It can be heated by a heating device and is accessible via a feed opening, which is preferably located in front of the housing. A flow channel leads from the substrate holder to the rear end of the housing. The heating device is configured to generate heat by thermal or catalytic combustion, and preferably in the rear region of the housing,
A fuel reservoir is located. The system further includes a substrate portion configured to be inserted into the substrate holder through the feed opening and containing the aerosol-forming material inside the envelope. The envelope has an air inlet and an aerosol outlet.

[0011] The energy required to heat the aerosol is derived from gaseous and / or liquid fuels, so that an economical and easily available energy carrier with a high energy density is available. Thus, the inhalation device may be of a light and handleable design such that it can be easily carried in a user's mouth even when it contains a full fuel reservoir. The rod-shaped housing is easily accessible and the user feels more or less smoking a cigarette or cigar with a cigarette tip. The substrate part is inserted into the heatable substrate holder in the front region of the rod-shaped housing, preferably via a feed opening located in front of the housing. This further enhances the feel of using a cigar or a cigarette with a cigarette tip. The substrate portion is heated via the heatable substrate holder to discharge an inhalable aerosol guided through the flow channel to the rear end of the housing.

In the rear region of the housing, the inhalation device can have a mouthpiece, which is connected to a flow channel, preferably so as not to generate an unpleasant high temperature for the user. Has poor thermal conductivity. Instead of the mouthpiece, it is conceivable that a filter configured as a filter mouthpiece can be inserted into the flow channel in the rear area of the housing. In one variation, the filters are inserted into the flow channel at different locations; such a design can also be used in connection with a fixed mouthpiece.

In a preferred design, the substrate holder of the inhaler has at least one heating surface, which is preferably hollow cylinder or groove-shaped. This substrate holder may for example have two heating surfaces arranged parallel to one another, the mutual distance between them being preferably adjustable. The setting of this distance may be done automatically, for example with the help of a bimetal strip, according to its temperature. In a preferred design, the substrate holder of the inhalation device has a casing with good thermal conductivity in these heating surfaces, the casing preferably being provided with holes. Is set so as to lean on the base portion inserted into the base member. Due to these deformations, between these heating surfaces and the zones of the base part which are located in the region of the heating surfaces (either directly via the heating surfaces or via the heat conductive casing) Guarantee good contact. These heating surfaces or casings, however, do not need to directly touch the base part; types in which the distance between the former and the base part is foreseen, for example, in which heat transfer occurs by radiation, are also possible. , You can think.

[0014] Preferably, the substrate holder of the inhaler has, behind these heating surfaces, a rear cavity into which the rear region of the inserted substrate part can be pushed. This design allows the user to inhale the released aerosol while heating the substrate portion. In this process, the user preferably
Each time a cigarette is smoked, the base portion is pushed slightly back further and the consumed portion of the base portion is received in the rear cavity until the entire base portion is consumed (smoked).

To prevent the base part from being pushed too far into the housing of the inhaler, the rear end of the rear cavity can be provided with a stop for the base part.

In the case of the preferred type, the heating surface of the suction device is designed to be heated by catalytic combustion of gaseous fuel and / or liquid fuel. Catalytic combustion avoids problems when controlling the flame from the heating device and is advantageous for small designs.

In the rear region of the housing of the suction device, a fuel reservoir, preferably refillable from the outside, may be arranged. Alternatively, a design is conceivable in which a replaceable refill cartridge containing fuel is mounted in the housing. As will be pointed out in detail in the claims, customary combustion substances which can be gaseous or liquid at room temperature can be used as fuel.

[0018] The inhalation device may have a switching device, which is connected to an ignition device and a valve device, the ignition device being set to ignite the fuel, preferably Actuating piezoelectrically, the valve arrangement is set to release fuel from the fuel reservoir. In the case of the preferred type, the switching device is purely mechanically designed and has a ring, which is axially movable on the front region of the housing, preferably It has poor thermal conductivity and can preferably be fixed in two positions. Thus, for example, the piezo-electrically activated ignition process can be triggered by moving the ring, the valve arrangement being simultaneously opened to release fuel for catalytic combustion; , Fixed, the valve device remains open and the heating process is continued. After a sufficient amount of time has passed (e.g., after a single cigarette), the user can release the ring by turning it back and pushing it back to its initial position, which is preferably achieved by the valve device. It is done with the help of a spring so that it closes again and the heating process ends.

[0019] Preferably, the front region of the housing of the suction device has an air inlet for the supply of combustion air to the heating device. The combustion gases (effectively carbon dioxide and water) exiting the heating device are added to the inhalable aerosol in a preferred form of the invention, and the preferred control of air, combustion gases and aerosols is to allow the user to remove tobacco. Can be achieved by sucking. In particular, in the case of catalytic combustion, the combustion gas is harmless because it contains harmful substances (eg, carbon monoxide) in small amounts. On the other hand, in a preferred form of the invention, these combustion gases are kept away from the inhalable aerosol.

In an advantageous design, the housing of the inhalation device has a window in front of a component (eg a heating surface) that ignites when the heating device is operated. Then
The user can easily monitor the operation state of the inhaler.

The housing of the inhaler can be composed of one or several parts. In the latter case, it preferably consists of two parts, for example the front region of the housing (where the heatable substrate holder is located) and the rear region of the housing (where the fuel An intermediate region between the reservoir (where the reservoir is located). The housing can be opened at the detachable connection, for example, for cleaning purposes. The material for the housing of the inhaler should be heat resistant. For example, duroplastics, multi-component plastics, hardwood, high-grade wood, root timbers and / or metals can be considered.

This base part is preferably cylindrical in shape, and its envelope is
It is arranged as a cylinder casing, the front face of which is set as an air inlet and an aerosol outlet. The envelope is preferably low porosity to air impermeable to avoid sidestream smoke. In its front region, the base part can have an insulating casing, which preferably protrudes beyond the front end of the envelope, so that the user can inhale the base part. No contact with hot surfaces when pushed back into equipment housing. The aerosol-forming material of the substrate portion may include a generally inert carrier or tobacco material and other additives. Preferably, the material has a high proportion of a polyol that acts as an aerosol former. This base part is
It is a thin fiberless cigarette that is customarily sold, and it is conceivable that the cigarette may contain a polyol in a proportion of 5% to 10% by weight. Details of possible designs of the base part are given in the claims.

In the following, the present invention will be described in more detail using embodiments.

FIG. 1 shows how the base part 1 is inserted into an inhalation device, which serves as a smoking device. FIG. 2 shows the base part 1 in more detail. In the case of a base part 1 of this type, the aerosol-forming material 2 is located inside a cylinder sleeve 3. The sleeve 3 is such that the front face of its cylinder is released, so that an air inlet 4 and an aerosol outlet 5 are formed.

The aerosol-forming material 2 is, for example, cut leaf tobacco (cut leaf).
tobacco), cut tobacco ribs,
It can contain reconstituted tobacco, or carrier material treated with aroma. Leaf and rib cuts can also be used in enlarged configurations. Both organic materials (eg, paper or cellulose fibers) and inorganic materials (eg, silica gel) can be used as carrier materials for the fragrance. Any mixtures of the components named herein can also be used. Numerous components and components for this aerosol-forming material are recited in the claims and numerous variants are possible.

To enhance aerosol formation, the aerosol-forming material 2 preferably comprises, for example, a generally inert carrier material (eg, aluminum oxide, silica gel, charcoal,
When using cellulosic fibers, lignin granules, zeolites, alumina or sepiolite or combinations thereof), a high proportion of polyol or some polyols (for example glycerin and / or Propylene glycol). When using tobacco materials, the preferred proportion of polyol is from 10% to 40% by weight. Other possibilities for enhancing aerosol formation are:
It is to use an aerosol-forming material that has a significantly higher moisture content than the equilibrium moisture content; for example, tobacco has an equilibrium moisture content of approximately 10% to
12%, but can be used with a water content of 20%. In this case, suitable packaging can be used to ensure that there is no water loss before use.

The sleeve 3 can be made of paper, plastic film or metal foil. Multilayer sleeves made from the components named herein can also be used. However, single layer sleeves made from paper or metallized paper are preferred. Low porosity or substantially air impermeable cigarette papers, which preferably have a high proportion of mineral additives, are particularly advantageous. This ensures that no sidestream smoke is produced, especially when the substrate part is heated and smoked.

In a preferred design, the base part 1 is surrounded in its front region (for example in the region of the air inlet 4) by an additional insulating sleeve (not shown in FIGS. 1 and 2). , Which preferably project beyond the front end of the sleeve 3. This insulating sleeve ensures that the user does not come into contact with the unpleasant hot surface when smoking, when he pushes the base part 1 deep into the inhaler device (see below).

It is also conceivable to use as the substrate part a thin fiberless cigarette, which is customarily sold, which contains a polyol in a proportion of 5% to 10% by weight.

In the following, two further design examples of the base part 1 will be described.

Example 1 American Blend Tobacco Mix (30% Burley Tobacco, 40%
(Including 20% non-expanded Virginia tobacco and 10% orientated tobacco) were sprayed together with 12% by weight of an aqueous casing containing 80% by weight glycerin. The tobacco was then cut to 0.8 mm width and dried to a moisture content of 12%. 180 kg of this cut tobacco,
It was mixed with 20 kg of expanded rib tobacco. A continuous strand having a diameter of 5 mm and a packing density of 200 mg / ml was prepared from this mixture using a paper tobacco strand machine.
Air-impermeable paper coated on the outside with aluminum was used as the sleeve. The continuous strand was cut into individual sections of 40 mm length.

Example 2 A paper leaf tobacco prepared by a known method and containing 12% of propylene glycol was cut at a cutting width of 0.8 mm and fed to the same paper tobacco strand machine as in Example 1. Then, together with the paper cigarette paper, the paper cigarette paper had an air permeability of 5 CU. This continuous strand is fixed length (diameter 6 mm
) To give substrate parts each having a length of 50 mm; the packing density was 240 mg / ml.

In principle, the use of a base part provided with a filter, which is customarily traded behind the aerosol outlet 5, is also conceivable. However, when such a base part is inserted into the inhalation device, it must be ensured that it is not this filter but the aerosol-forming material 2 in front of the filter that is heated.

FIG. 1 shows one type of inhaler 10 in a schematic longitudinal section. The inhalation device 10 has a rod-like or cigarette-shaped housing 12, which has a front region 14
And a rear mouth area 16. The rear end of the rear region 16 is designed as a mouthpiece 18 (see FIG. 1).

The housing 12 is preferably made of a heat-resistant material (for example, duro plastic,
Multi-component plastics, hardwoods, fine wood, rootwood and metals or several such materials). Important points are equipped with or consist of insulating material to prevent the user from coming into contact with the hot surface.

In this embodiment, the housing 12 is designed in two parts, a front area 14 and a rear area 16, which can be joined via a connection 20. The front region 14 and the rear region 16 of the housing 12 can be plugged into one another with a connection 20 (guide not shown in FIG. 1), where the projections engage the grooves and are associated with the front region 14. The specified position of the rear region 16 is guaranteed, and twisting is prevented. A thin-walled retaining nut, which meshes with external threads in the rear region 16, secures it. The insulating ring 22 greatly prevents heat transfer from the front region 14 of the housing 12 (which is heated during operation) to the rear region 16 with the mouthpiece 18. When the housing 12 is opened at the connecting portion 20, the heat insulating device 10 can be washed.

A feed opening 24 (through which the base part 1 can be pushed inside the housing 12) is located on the front face 23 of the housing 12. The substrate holder 26, which includes a guide sleeve 28 matching the outer diameter of the substrate part 1, serves to hold the substrate part 1. The heating surface 30 is configured as a hollow cylinder in this embodiment, but is arranged behind the guide sleeve 28. Behind the heating surface 30, the substrate holder 26 has a rear cavity 32 into which the rear region of the inserted substrate part 1 can be pushed.

An axially arranged flow channel 34 is provided in the rear region 16 of the housing 12.
Extending from the rear cavity 32 to the rear end of the mouthpiece 18.

The heating surface 30 is one component of the heating device, and in this embodiment operates as a flameless incandescent catalyst for heating the substrate holder 26. The combustion air for the operation of this heating device in the front region 14 via the air inlet 36 via the housing 1
You can enter 2. When the heating surface 30 is at a high temperature, it heats a zone of the base part 1 close to it. Thus, when the heating surface 30 is designed in this embodiment as a hollow cylinder, it heats the region of the base part 1 that is located just inside it. In this embodiment, the inner diameter of the heating surface 30 is larger than the outer diameter of the base portion 1. This heat is transported for the most part by radiation from the heating surface 30 to the base part 1. The heating surface 30 can also be arranged such that heat transfer takes place in heat transfer. In this case, if the heating surface 30 does not directly touch the base part 1, the casing is preferably provided with holes and is made of a material having good heat transfer properties (for example, aluminum), whose dimensions are: It is advantageous if it is arranged on the inside of the heating surface 30 (not shown in FIG. 1), which conforms to the base part 1 and preferably rests directly on it. Many variations of the design of the heating surface 30 are possible. Thus, several heating surfaces (eg, two heating surfaces arranged parallel to each other) can also be provided, or other shapes (eg, groove-like contours) can be selected for the heating surface. . The heating surface 30 passes through the outside of the base portion 1 to heat a zone of the base portion 1 located in that region (that is, heating).
It is essential that the heated gas (especially air) cause direct heating (as opposed to indirect heating drawn through this substrate part).

The fuel (eg, butane gas, pentane or isopropanol) required to operate the heating device is located in a fuel reservoir 38, which is located in the rear region 16 of the housing 12. The fuel reservoir 38 can be replenished via an outwardly directed refill pipe 40, which comprises a closure. In this embodiment, the fuel reservoir 38 is designed in the form of a ring, through whose axial region the flow channel 34 opens. Instead of the refillable fuel reservoir 38, a fuel reservoir designed as a refill cartridge can also be provided, which is inserted in its entirety into the rear area 16 of the housing 12. Alternatively, housing 1
It is conceivable to configure the entire rear region 16 as a disposable unit that is replaced when the fuel reservoir 38 is empty.

In order to supply fuel from the fuel reservoir 38 to the heating surface 30, the valve 42 that is deployed in the fuel line 44 connected to the heating surface 30 must be opened. In this embodiment, the front region 14 can be separated from the rear region 16 of the housing 12 so that the fuel line 44 must also have a separation point designed as a sealed connection 46.

A mechanical switching device including a ring 48, which is a poor heat conductor that is axially movable in the front region 14 of the housing 12, is used to ignite this fuel and activate the valve 42. Is done. The ring 48 has a gripping surface on its outside.
When pushing the ring 48 rearward (ie, in the direction of the arrow depicted in FIG. 1), the valve 42 opens to allow fuel to flow from the fuel reservoir 38 to the heating surface 50, while the piezoelectric igniter 50 is Activated, which initiates catalytic combustion of the fuel. The ring 48 can be locked in the pushed-back position by rotating it. The valve 42 remains open at this position of the ring 48 and catalytic combustion continues,
The heating surface 30 radiates heat even if the igniter 50 is not operating during this time. At the end of this heating process, the ring 48 is released and pushed forward by rotating it in the opposite direction. Valve 12 closes. Preferably, a spring, not shown in FIG. 1, presses the ring 48 forward. Valve 42 and igniter 5
The mechanical components for starting 0 are not shown in FIG. 1 for clarity.

If the user wants to use the inhalation device 10, first a new base part 1 (through the feed opening 24, until the rear zone of the base part 1 rests in the area of the heating surface 30) For example, pressing a special thin cigarette with a diameter of 5 mm and a length of 40 mm).
When the user first smokes and wants to inhale the smoke, the ring 48 is pressed onto the mouthpiece 18 and fixed by rotating it. As already explained, thereby, the fuel flows to the heating surface 30 and is ignited. Due to the heat radiated during the catalytic combustion, the zone of the substrate part 1 is heated in the region of the heating surface 30, so that the aerosol-forming material 2 emits a taste aerosol. When the user inhales with the mouthpiece 18, air enters the base part 1 through the air inlet 4 and through the aerosol outlet 5 of the base part 1, via the flow channel 34,
Carry this taste aerosol to the user. Preferably, via the air inlet 36,
Additional air that acts as a diluent coalesces. In this embodiment, the inhaled aerosol also contains carbon dioxide and water vapor from the catalytic combustion of the fuel. If the housing 12 has a window (this is not shown in FIG. 1 so that the user can see the heating surface 30),
Note that the heating surface 30 glows red when ignited, and then its color turns light red when the user sucks in the mouthpiece 18.

The user presses the base part 1 slightly towards the mouthpiece 18 before next sucking.
The rear smoking Zahn of the base part 1 enters the rear cavity 32, during which a new zone reaches the area of the heating surface 30. Therefore, upon next inhalation, the user will experience a fresh taste aerosol. To conserve fuel and avoid sidestream smoke, the user may counter-turn the ring 48 after each inhalation and push it forward so that the valve 42 closes. Can be canceled. When the base part 1 leans on the heat insulating ring 22, it will suck last. The user
The base part 1 can then be withdrawn from the housing 12 through the feed opening 24 and discarded.

Using an inhalation device 10 of the type described, the user, by inhaling with the mouthpiece 18, not only the outside air entering the base part 1 through the air inlet 4 and the outside air passing through the base part 1, The necessary flow of outside air entering the heating surface 30 (catalytic combustion) through the air inlet 36 is ensured. The combustion gas generated during the catalytic combustion is sucked into the flow channel 34 and merges with the intake aerosol as described above. Since this catalytic combustion occurs almost completely, the amount of carbon monoxide and other undesirable substances resulting from combustion in the inhaled aerosol is small, so that the transmission of such gases and aerosols is acceptable.

However, it is also possible to keep this combustion gas away from the inhaled aerosol. To do this, for example, a sleeve (
It can be made of metal with good thermal conductivity and connect the guide sleeve 28 to the rear cavity 32) so that this combustion gas is inaccessible to the flow channel 34. Preferably, this sleeve is in thermal conductive contact with the inserted base part 1. In this case, the wall of the housing 12 must have at least one outlet for this combustion gas. The desired flow from the air inlet 36 to this outlet via the heating surface 30 can be achieved by means of a temperature gradient (warm air flow).
